We haven't seen a year-to-year rematch since Super Bowl XXVIII (Dallas Cowboys vs. Buffalo Bills). Of course, that doesn't mean one -- or both -- teams won't take up residency at MetLife Stadium on Feb. 2, 2014.

How does it start?Aaron Rodgers and the Green Bay Packers are invited to San Francisco, where their season ended in blowout fashion in January. This is one of just two late afternoon games in Week 1.

Treacherous stretch: Right out of the gate. The Niners open with three consecutive playoff teams against the Packers, Seattle Seahawks and Indianapolis Colts (combined record of 33-15 in 2012). The Niners then have a road matchup with the St. Louis Rams, a team that gave them fits last season.

Weird quirk: The Niners don't face a team coming off a bye.

Did you know? This is the 49ers' last season at Candlestick Park. This isn't necessarily a bad thing.

Bottom line

The Ravens and Niners have challenging schedules, but it would be pushing it to say the league did either team a disservice. Eight primetime games between the two means America will get a very good look at both defending conference champs.

It's way too early to know how either side will fare in 2013 -- especially the retooled Ravens -- but both teams will be must-see TV in 2013.
